MK 1 Old School... Turbo



  Punto/Clio GTT
was supposed to be next weekend, but ive had a bit of a riff with my cousin so im gonna get my mate to paint it instead in a bodyshop, should hopefully do me a good quote.

probably best anyway, wasnt keen on painting it in my cousins garage, wasnt very big and the roof leaked, so less stress for me i spose

  Whichever has fuel
Dan, forgive me for not reading back, but is it mechanically ok? As in it starts and drives and runs?
 
  Punto/Clio GTT
yea all sound mate, needs an oil n filter change and a couple of electrical niggles, but runs fine. needs rear drum changing aswell as wheel bolt wont tighten up

£500 quoted for respray :\ more than i was expecting tbh for a mask n blast.

gonna be cheaper for me to just buy a compressor (£250-£300), air lines n water traps n just paint it myself at home. ill build a little enclosure, watch this space ;)

fair play for giving it a go, and even better, you will learn more

k done a couple of bits today

few questions, is this the turbo? im pretty sure it is but ill check anyway

IMAG0139.jpg



secondly im gonna be fitting an incar boost controller. from what ive read, i need to remove this actuator (think its called that), and extend the pipes to the inside of the car.
IMAG0137.jpg



now, from this actuator, i have a pipe running to the turbo (?)

IMAG0140.jpg



and a pipe running to the throttle cable unit thing

IMAG0142.jpg


ive got the hose plumbed into the bulkhead and ready to fit the controller, ive also plumbed in the hose for the boost gauge

IMAG0144.jpg



now. when i get the controller, will the IN nipple be for the hose at the throttle cable end and the turbo end will be the OUT nipple, or will it be the other way around? like which way does the air flow, fdoes it go from the turbo to the throttle unit or from the throttle unit to the turbo?

heres a picture of my rebuilt dash for anyone that helps, ta! ;)

IMAG0145.jpg



i also tested out an old boost gauge i had and bounced it off the limiter once and i hit 1.5bar?? im guessing thats way too high?

Hi there

Looking at it, it seems to be a gt turbo engine conversion is this correct? 1.4?

The answers you want depend on the conversion Tbh, you're running a carb so I'd stay away from adjustable boost as you run into all sorts of fuelling issues.
 
  Punto/Clio GTT
yea gtt. what my plan was to run a boost controller, have the max set to about 13psi and the bottom set to however low it goes.

is it safe to run it with the turbo basically turned off or does it not work like that?
 
  172 cup
Standard boost pressure is 9 psi so It's not really worth faffing about with adjusters as it's just something else to go wrong, t2s will run 16 happily, best advice I could give would be to remove any boost controllers and get it set up to run about 14psi.

With an ecu adjustable boost is fine as it will make the fuelling adjustmests for you
 
  Punto/Clio GTT
if it was £300-£350 id probably pay it, but for 500 i can get a compressor and everything i need and still have change, so no brainer really

This is the actuator mate:

This is a dump valve:
IMAG0137.jpg



You already have a boost controller installed by the way:
IMAG0140.jpg


The thing cable tied under the dump valve.
 
  Punto/Clio GTT
gah, bandwidth hit on photobucket >.<

so that thing is a boost controller? someone said there was another way to adjust the boost levels, either by the circle thing, or you can adjust it on something else?

i think im still gonna get an incar one as ive already fed the pipes through now! ill drop it down to 1 bar when i get it
 
  182/RS2/ Turbo/Mk1
You wont be able to lower the boost when you add the in car bleed valve, you will only be able to use it to bleed air off and hence RAISE the boost.

So to lower it you need to remove the controller in the bonnet, and set to the minimum amount you want on the actuator, then use the in car one to raise it from there and drop it back down again.
 
  Punto/Clio GTT
ok ideally what i want is to barely run the turbo day to day, like as low as possible. could i turn it down on the actuator to about 4psi, then with the incar controller, have it raise upto 1 bar? would that be possible? or would it be overfuelling way to much at 4psi and run like dogs**t?
 
  182/RS2/ Turbo/Mk1
Yes that would be possible, and the fuelling to a certain extent will correct itself, thats the point of the carb.
 
  Punto/Clio GTT
awesome cheers mate

as for adjusting the actuator, do i wind that big needle in with the nut thats on it or is there something on the other side?

meant to come back on and explain in a little more detail, my computer is having issues atm so replied from my phone, which was also having issue.

cheers chip, saved me a job :cool:

you can run with the boost turned down but will be gutless, the carb will adjust the fueling to a certain degree of course but the reason gtt's got labelled as unrealiable and always blowing up wasn't due to overheating problems, it was because people who didn't know about how the engine set up works upping the boost to silly levels, this made it run lean which increases combustion temps and makes the engine go pop. obviously you don't want to run high boost levels so really you'll be over fueling which will affect your mpg, as for other side affects I don't think you'd really have any problems at those boost levels.

seeing as the car has been stood for a while it might be worth getting it on a rolling road and getting you afrs check and carb tweeked, just to make sure all is working as it should be. I still don't really understand why you want to be able to adjust the boost but it's your car. might be worth joining a owners club which specialises in renault turbos, the joining fee will be well worth it with what you'll learn and save in labour repair bills ;)

im a member on r5gtt owners club, but it seems dead on there. i had a quick look on RTOC and it was like £25 membership and didnt seem very active either. i think im just comparing places to CS and expect every forum to give instant replies lol

i understand your concerns about the boost controller, but i want to have the car running as reliable as humanely possible. i thought lowering the boost and being able to up it to 14 (ish) psi would be alright for the engine, or am i just being a clown and just run it at 14psi always? i just dont want it to blow up lol

im 28 and i know these engines have a bad rep, but i dont drive like a lunatic all the time, this cars gonna be driving my kids around during the week, then of a weekend itll just be me, so i may give it some beans on the rare occasion and i want the power on hand. hence the 4psi daily car then running 14psi on tap on the incar boost controller. but i guess would the fuelling issue just be not worth it.

anyway, ill have a think about it.

im trying to adjust the actuator atm as its currently running 21psi (over 1.5 bar of boost)

i cant seem to see how you adjust it? ive tried to undo the nut further but it becomes very tight and i dont wanna snap anything.

if i wind the nut in (towards the actuator, then the nut doesnt reach as the thread runs out.

so from what i see, the thing that the nut pushes againsy (towards the turbo) is NOT threaded on that spline? its just a cover thats seized on yes? and when i force that nut, the thingy closes dropping the air pressure going to the turbo (or from it?)

heres pics anyway

so, this bar pulls out of the actuator, it seems spring loaded, im guessing pulling that out doesnt do anything as the thread ends before i can tighten the nut up on that side

imag0149g.jpg



when i pull the bar out, this happens, so im guessing it closes it, but instead of pulling the actual pin out, i need to tighten the nut up, yes?

imag0150o.jpg


heres the nut, the nut spins fine, i can turn it by hand. but when i get to the right side by the turbo it doesnt do anything, do i just give it some force with wd40 until it closes the thing by the turbo to lower the boost?

imag0152i.jpg



cheers lads, sorry if it seems like im asking dumb stuff, but engines aint my forte!
 
  Punto/Clio GTT
gave it some force but its just starting to bend the rectantgle pice of metal on the turbo thing?

do i need a new actuator, would that be best bet?
 
  Punto/Clio GTT
also fans aint working inside, i checked the block connector on the back and it looks fine

took the fan unit out, was stiff, spun it with fingers n wd40'd it, plugged it in, still nothing. checked all my fuses they all good.

am i right in thinking that i could test the connector with one of them screwdriver things with the ignition on? if i touch a live pin it will light the screwdriver up? that would tell me the fans getting power but the fans broken?
 
  Punto/Clio GTT
chippppp! f**king b*****d thing snapped! lol new actuator? they hard to source? one of the bolts looks like an absolute ballache to get to aswell :(

imag0164s.jpg



got rid of the valve thing aswell n just put a temp piece of pipe in

Dont panic mate, you dont need a whole new actuator, just a new rod end, they arent very dear and TBH I probably have a spare one knocking around somewhere if you arent in too much of a rush for it.

So see if you can unwind the old end, and if you can I'll try and find a new one for you.

If you cant unwind it, then you'll have to get the actuator off though im afraid.
 
  Punto/Clio GTT
i tried holding the thread with pliers and it was just spinning when put a screwdriver in the hole and tried to undo it. so i got a spanner on the nut and tried to undo it that way and it just snapped. do i clamp the nut or will the nut just spin, so clamp the thread?

aint in mega rush for it.

i think ill just drop the actuator off and get it off that way so i dont damage the actuator itself
 
  Punto/Clio GTT
i got it off!!!

stripped a few bits down, intercooler out, header tank out, rad hose off and coolant flushed with all pipes flushed out with hosepipe.

quick clean n put back together

imag0165db.jpg


imag0168uj.jpg



offff!!!

imag0169fm.jpg


imag0171w.jpg



also noticed that this is broken, its from the turbo, it all tightens up ok though, does it matter?

imag0173x.jpg



next i had a f**king great idea... to clean the header tank..... with RICE

imag0174kn.jpg



before

imag0175v.jpg



after

imag0177la.jpg


so it sort of worked, to an extent, didnt work aswell as id have liked though :\

imag0181hd.jpg


anyway, built it all back together, was well pleased of myself, turned the engine over to check it........

imag0182u.jpg



forgot to put the oil pipe on the bottom of the turbo! oil, everywhere! i was like fuckkkkkkk, hosed it all down and its alright, needs an oil change anyway

so yeah, productive day and didnt break anything except put oil all over the side of my house n subframe :\

also, flickering battery light on idle, whats that, alternator? bad earth?

also, on idle, obviously the chokes on til it comes upto temp, but when i turn the choke fully off, it will idle at around 400 maybe 500rpm, it like, nearly stalls but doesnt, then itll jump upto like a 1000rpm then go back down to 500 or so. that normal?

Idle jumping around could be you were too quick to put the choke back in and its not quite ready, or it could be a tune problem at idle, welcome to the world of carbs, lol

flicking battery light is lack of charge, could be alternator, or could be the belt slipping a bit at idle, or could be poor wiring connections
